’A Day in the Light’ Videos Highlight How Scientists Use Light in Experiments

In recognition of the International Day of Light ( @IDL2019 ) on May 16, the Department of Energy’s Lawrence Berkeley National Laboratory ( Berkeley Lab ) is highlighting how scientists use light in laboratory experiments.

From nanolasers and X-ray beams to artificial photosynthesis and optical electronics, Berkeley Lab researchers tap into light’s many properties to drive a range of innovative R&D.

In the three videos displayed below, you will learn how light drives the science of Berkeley Lab’s Advanced Light Source (ALS), a synchrotron that produces many forms of light beams. These light beams are customized to perform a variety of experimental techniques for dozens of simultaneous experiments conducted by researchers from across the nation and around the world.
